I don't know what vet said that early fixing hinders the development of the urinary tract, but he obviously forgot a lot of things he/she should have learned in school. Extremely rare vulvar hypoplasia (still not actually proven) and urinary incontinence (not due to development, usually idiopathic response due to an already congenitally narrow or hypoplastic urethra, and still very rare) are the only things reported, and the studies that support them are still shaky, even. That's balderdash.
Early neuters are prone to incontinence, sarcomas, arthritis, etc.
Sources? As in *multiple, agreeing, statistically significant, peer-reviewed, large-case-number studies*, not one small study done in an unpronouncable country, not a couple websites and not grandma's anecdotes. What about the reduction of mammary tumors in female dogs to near 0% with spaying early? Fewer vaginal prolapses, no uterine cancer or metritis, a marked reduction in hormonally-drive cancer? Early spay has also been linked to control of other diseases like diabetes, epilepsy, and demodecosis.
And markedly reduced incidence of prostatic hyperplasia, and perineal hernias, and perianal adenomas in dogs neutered early?
The only mildly (but exaggereated) truth to what you said is that certain giant breeds dogs neutered early can have an increased incidence of hip issues, and the occasionaly spay incontinence in the female (which is becoming more linked to technique and congenital/preexisting and exacerbated urinary structural issues than age).
